KYKY Technology Co., Ltd. was established in 1958 as an early pioneer in vacuum technology and electron optics in China. Originating from research institutions in Beijing’s Zhongguancun technology district, KYKY developed China’s first commercial scanning electron microscope (SEM), vertical turbomolecular pump, and helium leak detector.
For more than six decades, the company has operated specialized development and manufacturing facilities producing electron optics instruments and high-vacuum equipment. KYKY supplies analytical laboratories, university research centers, and industrial facilities in domestic and overseas markets.
